IMPROVEMENT IN COOKING-STQVES.

The Schedule referred toda these Letters Patent and making part of the same.

To all whom 'it ma/y concern.-

Be it known that I, GEORGE W. WALKER, of Boston, in the county of Suolk and State of Massachusetts, have invented Improvements in Cooking-Ranges and Stoves; and I do hereby declare that the following, taken in connection with the drawing which ac-4 companies and forms part of this specification, is a description of my invention suficient to enable those skilled in the art to practice it.

My invention relates to certain details of construction of Acooking-stoves or ranges and their appliances, one of which details has reference to the combination', with the oven-door or with either vertical plate of the stove, of a sliding shelf, that may be dropped down and concealed behind the outervplate of the door or stove when not in use, and may he drawn up and dropped down to and maintainedin ,horizontal position, to serve as a shelf for the support ot plates, pots, or other utensils used with or about a stove,`

one part of the invention consisting in such a sliding shelf.

Another detail has reference to andconsists in the arrangement of a line-pipe behind the stove, and the construction ot' the stove with reference to the snpport and location of such pipe, the stove being made with a recess extending vertically from theY top to bottoni of the stove, at its rear or end, to receive the dnepipe, and permit the stove to be set as closely or nearly as closely to the wall of a room as if the rear flue-pipe were not employed, and the foot of the due-.pipe being supported upon a step, which is preferably made removable, or is removably attached tothe stove-plate, so that the luemay he made of any length or set at any desirable height.

rlhe invention also consists in a coupling and draughtregulating box, which rests upon the stove top, and has the flue-flange of the stove 'passing' through its bottom plate, and which is open at its rear and has the rear tine-pipe connected to and opening into it.

The drawing represents a stove embodying my improvements.

A shows a perspective elevation of the stove,

B is a central vertical section of the rear fine-pipe and the due-connecting and draughtregulating box.

O is a plan and sectional view of said due-pipe and box.

D is a view of the flue-supporting step.

a b denote the vertical) front and end plates;

c, the top plate; and

d, the hearth-plate of an ordinary cooking-stove on range.

. e is the oven-door.

The oven-door is or may be made with an inner plate, between which and the outer plate ruins a shelf, f, which extends through an opening, g, at the top of the door. By taking hold of a handle or knob, h, the shelf lcan be raised, and when almost` withdrawn from the doory it is turned down until it reaches a horizontalposition, in which position it is retained and sns- `tained by the weight of the overhanging part of the shelf, and `by its bottom side resting .on the edge i, and its upper side adjacent to its inner or rear edge bearing upward against the top plate of the door;

At the end of the stove isseen another shelf, la, sustained in horizontal position by resting upon the top edge of the plate,` and bearing against the under surface oi' a top plate, Z, this shelf sliding down through an opening made at vthe angle of the plate l, and the end stove-plate b, and bengconcealed behind said end plate, or ybetween such plate and the end wall ot the oven. When the shelf is thus concealed within its pocket, itanswers to prevent escape ot' heat by radiation from thev plate b. The stove may be made with either one or more of these shelves, which may be* combined either with the oven-door or with one o1"- more of the vertical plates of the stove, or with both door and stove-plates. They. are always useful for the support of dishes and other articles, and when not needed are readily dropped into the pockets or spaces provided for their reception and concealment.

In order to provide for attachment of a vertical lluel pipe without occupying space therefor back ot' the rear plates of the stove, I cast the rear plate m with a recess, n, extending vertically from top to bottom ofthe plate, and in this recess I place the fine-pipe o, which may be connected with the chimney-flue hole by a short pipe or flange, p, placed at a height corresponding to the height ofthe line-hole.

The vertical flue-pipe o rests at its lower end on a step, q, which step is preferably made of' cast metal, and is preferably fastened to the stove-plate by a dove-v tail connection', which enables it to be readily removed,

The step is providedwith a -top ring or Harige, lr, to'

receive the lower end of the flue-pipe. The part of the flue-pipe o belowthe dange p serves as a sootchamber, to receive such ashes and soot as may pass through the stove with the volatile products ot combustion.

The upper part of the flue-pipe is connected to the outlet of the stove by a box, s, which maybe fastened to and forms part of the pipe o, the box and pipe communicating as seen at t, and the flue-flange u at 'at-wt didn,

At the front of the box are sliding doors w, by opening which, more or less, the draught may be diminished and regulated at pleasure.

C' laims.

1. In combination with a cooking-stove or range, a sliding shelf, substantially as described.

2. A stove, having a flue-pipe recess, n, substantially asshown and described.

3. The combination, with a stove, of an auxiliary flue-pipe, o, brought within the plane of tbe vertical stove-plate or the adjacent sides of the plate, substantially as shown and described.

4. The combination of the flue-connecting box and the vertical luevpipe relatively arranged, substantially as shown and described;
